CLOTH-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 457,899, dated August18, 1891.

Application filed October 10, 1890. Serial No.367,676. (N0 model.)

To all whom it may concern:

Be it known that I, HIRAM N. ELLIOTT, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Cloth Cutting Machines, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to improvements in cloth-cutting apparatusdesigned for cutting several layers of cloth at one operation; and itconsists in peculiarities of arrangement and detail construction ofparts, all as hereinafter more particularly set forth, and specificallypointed out in the claim.

In the annexed drawings like letters of refence indicate correspondingparts in all the views, in which- Figure 1 is a side elevation of myimproved cutting-machine, showing the overhead trackway and actuatingmeans. Fig. 2 is a front elevation, partly in section; and Fig. 3 is asectional view taken on line a: :11, Fig. 1.

In this class of devices it is highly important that the cutter shall berun at a high rate of speed and be free to travel in any di-' rectionover the table on which the cloth to be cut is resting, so as to followclosely the lines marked out from the pattern. To accomplish thesedesired ends, the cutting mechanism and actuating devices should be assimple and compact as possible, and to that end I have devised theinvention herein'referred to.

Suspended at a convenient distance above the operating-table I providethe track-rail I, which may be secured to the table or otherwisesupported, as best adapted to circumstances. This track-rail is providedwith adjustable hangersi i, from which hang pulleys J .I, over whichruns the driving belt or cord. (Shown in the drawings.) Running on thetrack-rail I is a hanger G, provided with a.

bracket G, in which is journaled the grooved pulley H. The beltj is heldin frictional contact with said pulley H by means of the idlers h h,over which runs said belt j for actuating the pulley H.

Power is communicated from the pulleyH to the cutting-machine by meansof the flexible shafting F, which is secured to the journal ot' thedriving-pulley H at one end and to the vertical solid shaft 61 at theother end by means of the collars e 6. At the lower end of the shaft d Iprovide a bevel-gear D, which meshes in a pinion D on the horizontalshaft d, and on one end of said shaft 01' I secure the rotatorycutting-disk G. The vertical shaft d is held in the standard B inboxesbb, which are removable at will for purposes obvious to one skilledin the art. The shaft 01 is provided near its lower end with thecircumferential channels Z, and an anti-friction bearing is providedthere by the use of the wellknown Babbitt-metal filling, (shown at m,) 6which is caused to conform to the contour of said shaft within the lowerbox b, (shown removed in Fig. 2,) while the horizontal shaft (6 istreated in the same manner, as shown at m.

Projecting downward from the standard B are the supporting-standard Aand shoe or runner A, which rests at the forward end on the cuttingtable and at the rear end on the rollers a, which run on said table.This latter is adjustable vertically in its re- 7 5 lation to the axisof the disk C by means of the set-screw a passing down through therearward extension of the standard 13,110 which the supporting-standardis secured by an ordinary dovetail joint, so as to be free to movevertically into the required position, in which it is held by thescrew-threaded projection of the handle E.

In practice, my invention is operated much as are the cutting-machinesnow in use, but I find that by substituting the overhead trackrail andflexible shafting for the propelling devices now in use I am enabled tomanipulate my machine with greater ease and to a more exact pattern thanthe devices referred 9o toare capable of, on account of the source ofpower being removed from the table on which the machine travels and theease with which the flexible shafting may be adjusted to any desirableposition for the successful operation 9 5' of a cutting-machine of thisclass. Again, the track-rail I may be suspended from the ceiling or heldabove the floor at the proper distance,and the cutting-table may bechanged in its relation to any fixed point on said I00 track-rail, andthe hangers i i and sheave G may be advanced along said rail toaccommodate themselves to the changed position of the table.Furthermore, the cutting-disk C wears away in use the shoe A may beraised by means of the set-screw c aforesaid to compensate for suchwear.

Attached to the rear face of the standard A is a handle E, which isprovided with a screw-threaded extension fitting into a screwthreadedopening in said standard and hearing at the extreme inner end againstthe tenon of the standard B, so that the parts A B may beheld againstaccidental displacement vertically, and said handle is used to guide themachine in operation.

Having described my invention, what I claim-as new is- In acloth-cutting machine, an overhead track, a hanger 011 said trackcarrying a driving-pulley, a flexible shaft connecting said the surfaceof the cutting-table, all constructed and combined substantially asspecified and shown.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this it'll day of October. 1890.
